This might sound silly (or stupid on my part), but on my 5 year old P4
machine, I had all sorts of problems in system lag (with and without
Compiz). It has 32MB of shared on-board video ram (Intel 915 chipset).
The problem was that the video ram was only set to 8MB in the bios.
Once I upped that to 32MB, the lag essentially disappeared and it
became much more stable. I can run almost all Compiz effects on it
without much problem although xfwm4 works better for me so I use that
instead. Granted, 32 is a lot more than 16. You might just want to
check the bios and make sure that all 16MB is getting used.
